Sub-steps:
- Visually inspect the steering rack and pinion for any signs of leaks or damage.
- If damaged, remove the steering rack by:
  - Disconnecting the steering linkage.
  - Removing mounting bolts and any necessary components obstructing access.
- Install the new steering rack, ensuring proper alignment and torque specifications.
- Reconnect the steering linkage and torque all bolts to manufacturer specifications.

4. Inspect and Replace Tie Rod Ends and Ball Joints

Sub-steps:
- Raise and secure the vehicle. Remove the front wheels to gain access.
- Use a ball joint separator tool to disconnect the tie rod end from the steering knuckle.
- Inspect for play and wear; replace if necessary with new components.
- Reassemble by reversing the disassembly steps and ensuring proper torque settings.

5. Check Power Steering Pump

Sub-steps:
- Locate the power steering pump and inspect for fluid leaks or unusual noises.
- If the pump is malfunctioning, remove it by disconnecting the inlet and outlet hoses and unbolting it from the engine.
- Install the new pump, reconnect hoses, and refill the power steering fluid.
